Q

Types of SCBA, characteristics of each? 5/4

A
  1. Closed-circuit systems
    • Also known as re-breather apparatus
    • Uses dried compressed air or an oxygen source stored in a cylinder.
    • Exhaled air in a re-breather apparatus stays within the system. Carbon dioxide is ‘scrubbed’ from the exhaled and the air is then recycled into the inhaled air.
    • Provides longer air-supply duration then open circuit.
    • This system is not used by the Edmonton Fire / Rescue Department; however it is used by the City in the water & sanitation services.
  2. Open circuit systems
    • Uses dried compressed air stored in a cylinder.
    • In an open-circuit SCBA exhaled air is vented through a regulator to the outside atmosphere.
    • This system is used by the Edmonton Fire / Rescue Department.
  3. Supplied air systems (SABA)
    • Uses dried compressed air stored in a cylinder.
    • Air is supplied to the SCBA via a hose connected to an air cart or other large air supply cylinder.
    • This system has limited use by the Edmonton Fire / Rescue Department on Ladder apparatus

Q

Types of standpipes including connection diameters?

A

• Dry system – not filled with water until needed in firefighting. Used only by firefighters. Must be manually charged by fire department.
• Wet system – standpipe is filled with water and is pressurized at all times.
• Wet/Dry Combination system – Portions of the system are pressured with water and other portions are pressured with air.
The standpipe system can also be divided into one of three classes.

  • Class I - provides 65mm hose line connections to supply water. These are usually found in the stairwells of the high rise structure or at dedicated areas within a warehouse.
  • Class II – provides 38mm hose cabinets that may be used by either occupants or firefighters.
  • Class III – provides both a Class I and Class II standpipe system – hose cabinet and standpipe connection. The 65mm connection may be in the stairwell or found in the hose cabinet.

Q

Expand I.D.E.A.S?

A

I.D.E.A.S.
 Integrity - What is the integrity of the anchor point? How is it rooted to the ground or building? Does it have sufficient mass to withstand the force that may be applied to it?
 Direction of Force – What is the direction of the force of the load upon the anchor? The anchor should be in line with the force being applied to it or any anticipated direction of force. Incorrect alignment may cause torqueing forces to the anchor, unequal loading of the anchor points or a pendulum of the rescue load.
 Equalization & no Extension - The anchor legs should have equal tension placed on both legs. This will enable the anchor points to share the load of the system. Also, there should be no extension to the system. Extension refers to the movement of the focal point, should one anchor leg fail there should not be any extension of the anchor legs causing high impact forces to be placed on the remaining anchor point.
 Angles - Examine the anchor system for “critical angles.” Critical angles increase the force of the load on the anchor points. This may cause a failure of the anchor system.
 System of anchors - What type of anchor system is required for the situation, and what are the advantages and disadvantages of designed system?

Q

Methods of size up?

A

Command uses three methods to gain information on the fire ground.
1. Visual Factors: Information Fire Command can see from the command post
• Type of building – construction, occupancy, obvious outside hazards.
• Location, volume, velocity, density, and color of the smoke coming from the structure
• Weather

  1. Reconnaissance Factors: Information received from other officers on the scene, or others assigned specifically to get information requested by command
    • Crews inside the structure will relay fire, smoke, & heat conditions to
    Command
    • Information that is gathered by crews from occupants exiting the structure, bystanders, and other non-departmental services involved in the event.
  2. Pre-Fire Assessment Factors: Pre-fire planning information that is determined in advance of the incident.
    • Pre-fire planning information gathered from pre-fire inspections will afford information such as life hazards, numbers and locations of occupants, access to the structure, floor plans, and the nature of interior and exterior exposures.

Q

Define REACT and PASS in reference to fire extinguishers?

A

REACT
 Rescue – initial evacuation of people in the room containing the fire
 Ensure door is closed - after evacuation close the doors to the room to reduce the risk for fire spread and to extend a tenable atmosphere in other rooms for evacuation.
 Activate alarm – activate the fire alarm system in the building. If there is no system have a designate notify others in the building.
 Call 911 – activate other Emergency resources in the event the fire extinguisher cannot contain the fire, to insure that professional resources are on their way.
 Try to Extinguish – return to the fire room and attempt to use the appropriate (class & rating) extinguisher to control the fire.

PASS
• Pull Pin – break the witness wire and pull the safety pin.
• Aim – aim the nozzle of the extinguisher towards the
base of the fire.
• Squeeze – squeeze the trigger of the extinguisher.
• Sweep – direct the extinguisher stream at the base of the
fire and sweep the stream back and forth to cover the
width of the fire base and into the burning material.
Apply the extinguishing agent until the fire is out or the extinguisher is exhausted.
Back away from the extinguished or suppressed fire.

Q

Loads and forces associated with buildings?

A
  1. Fuel load
  2. Structural load
  3. Dead load
  4. Live load

Impact, Static, and Repeated Loads

  1. Impact loads are sudden, one-time, short-term bursts of pressure that can produce very high stresses, especially when applied laterally.
  2. Static loads are gradual or constant pressures applied over the long term.
  3. Repeated loads are pressures applied intermittently over a period of time.
  4. Compression loads squeeze and shorten a member.
  5. Tensile loads pull apart or lengthen a member.
  6. Shear loads cause the planes of the member to slide past one another.
  7. Concentrated loads are focused in one small area, rather than spread across the length of the structural member.
  8. Axial load is a direct, even pressure applied to the center of the structural member’s cross section at a right angle to that center of the plane. It can be either tensile or compressive.
  9. Eccentric load tends to bend the structural member. It is a direct, even pressure applied to one side of the member, at a right angle to the cross section but not centered on it.
  10. Torsional load is a twisting pressure applied, at an angle, to any place other than the center of the structural member. The twisting action creates a shear load in the member. Torsion often causes extensive collapse.
  11. Suspended loads use rods and or cables to connect the suspended load to a main beam. The connectors can carry heat into the wood beam and ultimately cause a heavy suspended load to fall. Loads may also be suspended from bar joist trusses that can be greatly weakened by heat and flames.
208
Q

Types of walls and related terms a typical sizing?

A

Wall Materials

  1. Concrete walls may require a pneumatic (jack) hammer; where as a metal wall may require only a reciprocating saw. In some cases, a masonry wall can be breached with a battering ram.
  2. Brick and stone walls are, for the most part, veneer walls and are easily breached with properly selected tools. Most entries can be accomplished with normal firefighting tools and/or power saws.
  3. Interior walls are usually made of a wood frame with a gypsum board (drywall) cladding. Standard fire fighting tools such as an axe will accomplish the breaching.
  4. Walls made of fire-resistive materials are used to divide structures into compartments. They may therefore block or retard the spread of fire with in the structure. Breaching this type of wall may promote the spread of the fire with in the structure.

Hot Zone
A restricted area that represents danger to life or health. The Hot Zone is the first zone established by the first responder. It is based on the information they receive on route and first on scene. The Hot Zone can be a yard, city block or a whole floor of a building. The Hot Zone can always increase or decrease, but must be clearly established and maintained until 2nd Responders arrive. The Hot Zone is established using the red banner guard located on the pump No one shall enter the Hot Zone until Decon is set up; this includes the public, media and all Fire Personal
Warm Zone
Limited access contamination reduction zone. If decontamination is required after entering the Hot Zone it takes place in the Warm Zone
Cold Zone
Support or green zone. This is the area around the other zones where the work for supporting this incident takes place. The use off the yellow banner guard is recommended for this. The public and media are still kept out of this area.

266
Q

4 high rise ventilation effects?

A

Thermal layering
In a high rise heated smoke and gases will rise until their temperature and pressure equal ambient air. When this equalization occurs, the smoke will cease to rise. Smoke and products of combustion if remain cool will bank downwards from the state of equilibrium and contaminate lower levels.
Natural Stack Effect
Cooler outside air Hotter outside air

Reverse Stack Effect
Hotter inside air Cooler inside air
Mushrooming
Mushrooming is similar to stratification but the cause of lateral and downward migration is a physical barrier and not temperature / pressure equalization.

located on top of the piping
and sprays water into a
deflector that sends it back
down. Of course, if an
upright sprinkler is located in
any other position, the water spray would not be directed downward to the fire
3. Sidewall Sprinkler Orientation

A
  • *1. Offensive Mode**: Aggressive containment, confinement, fire control, and/or rescue operations. Activities are planned to attack and mitigate the problem.
  • *2. Defensive Mode**: Less aggressive techniques of diking, damming, and diverting are used to reduce the impact of the incident. The incident commander gives up ground to the incident for greater safety of responders and the public.
  • *3. Non-intervention**: In industry, non-intervention is not usually thought of as an option. However, with hazardous materials response, taking no action other than limiting access may be the appropriate action to take. All incidents will end eventually. The wise commander will try to balance the risk to people and the environment against the effect of doing nothing.
288

Methods of fire detection?

A

Fixed Temperature Detection
 The basic fire detection used in wet or dry systems, and a fusible link is the detection device.
Rate of Rise Detection
 Heat actuated devices operating on air pressure increase.
 Common for special hazard systems.
 It is fast, dependable, and positive in operation.
Smoke Detection
 Recommended for some hazards where smoldering fires, which burn with little or no flame and no discernable heat, may cause considerable damage.
 Used where fires give off smoke before they burst into flame.
 Detection is through use of a photo-electric cell.
Flame or Flash Detection
 Utilized in extremely hazardous occupancies where extinguishment must start immediately.
 It is commonly used in plants making explosives or munitions
 Is currently used for protecting the hazardous rolling operation in the manufacture of jet-propulsion powder.
 Flash detectors operate a fire-fog system that extinguishes fire in under a second
 Detection is through the use of a photo-electric cell.
Vapor Detection
 Indicates the concentration of combustible gases in the air surrounding hazards where highly flammable liquids or gases are stored, handled, or used.
 The detection device constantly samples the air in these locations sending a reading to a remotely situated control panel.
 When the concentration near 50% of the L.E.L. (Lower Explosive Limit) an alarm sounds warning personnel and allowing a window of opportunity to correct the problem.
 When the concentration reaches 75% L.E.L. the fire protection system operates.
